Does Silverlight 3.0 support WebHttpBinding for WCF RESTful services?

              No. http://msdn.microsoft.com/en-us/library/dd540823(VS.95).aspx Believe it is a security restriction.

              The whole point of WebHttpBinding is to allow a server to expose http endpoints.  Silverlight can consume http services.  There is no support for doing "Add Service Reference" from a Silverlight client to a WCF service using WebHttpBinding because that would be pointless.  I downvoted your answer because the fact that this capability does not exist has nothing to do with security.

                Fair point, but maybe a comment to that effect would have done. :)
